Traffic Diversions as Guiniguada Viaduct Undergoes Essential Repairs
Traffic will be diverted on the Guiniguada Viaduct in Las Palmas de Gran Canaria due to essential waterproofing work, which commenced on Sunday. The northern lane closures will last until mid-August, forcing vehicles to take alternative routes.
Drivers coming from the south must divert from Barranco Seco via the GC-31, passing through the San José tunnels to reach Avenida Marítima and then moving onto Julio Luengo towards the north. The Cabildo announced that southbound lanes will close from August 16 until the end of the month.
This project, led by the Gran Canaria Cabildo’s Public Works and Infrastructure department, aims to waterproof the viaduct’s two decks—an essential improvement since the bridge has never had this protection since it was built. It currently accommodates more than 130,000 vehicles daily.
The waterproofing work will cover over 18,000 square metres across both decks and is expected to be completed in just eight to nine days for each lane—a significant reduction in time compared to usual practices. To achieve this, the Cabildo has arranged with Lopesan Asfaltos y Construcciones to double the workforce to 20 specialised workers per shift, in contrast to the typical five or six.
August, a month generally less busy on the roads, was chosen to minimise disruption. Vice President Augusto Hidalgo urged citizens to remain patient and consider alternative routes before driving.
The project includes asphalt milling, the installation of waterproof sheets, and replacement of expansion joints, with a budget of €2.2 million. This repair work is part of a broader €18.7 million scheme to resurface 11 kilometres of the Circumvallation that has been ongoing at night for several months.
Drivers are advised to plan their journeys, explore alternative routes, and use public transport if possible to alleviate traffic congestion throughout August.
